摘要

We present the main performance aspects of the sensitivity and dynamic range of the Square Kilometre Array (SKA). The sensitivity and dynamic range of a radio astronomy interferometer are affected by different sources of errors and noises. A general description of these effects is given, focusing on the direction-independent effects. (C) 2022 Society of Photo-Optical Instrumentation Engineers (SPIE)
